The benzylation of benzothiazole(oxazole, imidazole)-2-thiones with 3,5-di-tert-butyl-4-hydroxybenzyl acetate involves either the sulfur or nitrogen atom depending on the reaction conditions. The S- and N-benzylation products of benzazole-2-thiones are kinetically and thermodynamically controlled products, respectively. The use of 3,5-di-tert-butyl-4-hydroxy-benzyl acetate allows sterically hindered
苯并噻唑(恶唑,咪唑)-2-硫酮与3,5-二叔丁基-4-羟基苄基乙酸酯的苄基化取决于反应条件而涉及硫或氮原子。苯并-2-硫酮的S-和N-苄基化产物分别是动力学和热力学控制的产物。使用3,5-二叔丁基-4-羟基苄基乙酸酯可使苯并唑-2-硫酮的位阻羟基苄基衍生物通常在比已知合成方法更温和的条件下合成。
